Analyse the following observation table showing variation of image distance ( )v with object distance u in case ofa convex lens and answer the questions that follow without doing any calculations:S.No. Object distance u ( )cm Image distance v ( )cm1. -100 +252. -60 +303. -40 +404. -30 +605. -25 +1006. -15 +120(i) What is the focal length of the convex Lens? Give reason to justify your answer.(ii) Write the serial number of the observation which is not correct. On what basis have you arrived at thisconclusion?(iii) Select an appropriate scale and draw a ray diagram for the observation at S.No.2. Also find the approximatevalue of magnificatio
